Karin • Isabella 12/31/17 💖 Cora 👼 Baby 3 Due 9/8/23
Just had my 13 week ultrasound for my NT screening! Down syndrome and thriscomy came back negative! Tech said she's 80% sure it's a girl 😊 any guesses? Apparently the numb is less then a 30 degree angle for girls and more than 30 for a boy... heart rate was at 155...Anyone else's baby girl have a similar ultrasound like this?
